Depressing on the Compression test. At least you know. Get or borrow a leak down tester to prove where the leak is and check for tight tappets on that cylinder. It will not run beautifully until you fix it which will be a head off re-build if it is not the tappets which suggest valve recession anyway. NB if you rebuild fit NEW exhaust valves. The VX sodium filled valves suffer from the heads breaking off from old age which gets very messy.

Hi Nigel, Return it! The non NS version is for axle units or gearboxes rated for GL5 with no Brass in the Synchroniser assemblies. GL5 oils can attack our Brass synchros forcing a gearbox re-build. We all make mistakes and you managed to not put it into the car.
